Security clearance requirements
Any student applying for a US visa may be required to undergo "administrative processing" or security checks. Graduate students majoring in "sensitive areas of study" as determined by the U.S. government are especially likely to be subject to this process. Your field of study (especially doctoral students majoring in a STEM field) might require your visa application to undergo a security clearance review.
